What happened
Maritime navigation restrictions imposed around Anak Krakatoa volcano
Local port authorities issued warnings requiring ships traversing the strait to exercise heightened vigilance due to potential navigation disruptions from volcanic activity. A 3-kilometer exclusion zone around the volcano was established prohibiting vessel entry.
Geological agency warns of potential volcanic activity intensification
Lana Saria, head of the geological agency, indicated that monitoring instruments continued recording seismic activity indicating magma movement within the volcanic system. She stated that while seismic activity indicates movement or release of volcanic fluids, the timing, magnitude, and nature of the next eruption cannot be predicted with precision.
Jakarta airport extends flight suspension to 17:30 local time
Jakarta's Soekarno-Hatta International Airport announced an extension of flight suspension operations until 17:30 local time (10:30 GMT) on Sunday, September 6, as over 200 flights and 20,000 passengers had already been affected by the volcanic ash.
Sixteen international flights cancelled from Jakarta due to volcanic ash
Sixteen international flights were cancelled, seven were delayed, and five were rescheduled following airport closures at Soekarno-Hatta International Airport in Jakarta. Affected international routes included connections to Doha, Sydney, and Kuala Lumpur, with Singapore being the most affected destination.
Sixteen domestic flights cancelled at Bali and Lombok airports
Flight disruptions extended to Lombok and Bali airports, with sixteen domestic flights to and from Bali cancelled due to volcanic ash affecting airspace operations in the region.
Anak Krakatoa volcano erupts in Indonesia with lava flows and audible detonations
Anak Krakatoa volcano, located in the strait between Java and Sumatra islands, erupted on Saturday with lava flows and detonations audible up to 700 kilometers away. Two additional eruptions were recorded on Sunday. The volcano has experienced sporadic activity since its emergence in the early 20th century within the caldera formed by the 1883 Krakatoa eruption.
Six Indonesian airports suspend operations due to volcanic ash from Anak Krakatoa
Indonesian authorities suspended activities at six airports on Sunday, September 6, including Jakarta's Soekarno-Hatta International Airport and three others in the capital, plus international airports in Bandung and Radin near Bandar Kampung, Sumatra. The suspension was caused by volcanic ash dispersal in the airspace, which is dangerous to aircraft engines. The suspension affected 209 aircraft movements and over 22,000 passengers.
Volcanology agency warns seismic activity indicates potential for further eruptions
Lana Saria, head of Indonesia's geological agency, warned that volcanic activity could intensify as monitoring instruments continued recording seismic activity indicating lava movement within the volcanic system. She noted that while seismic activity indicates movement or release of volcanic fluids, the timing, magnitude, and nature of the next eruption cannot be predicted with precision.
Maritime authorities issue navigation warnings for volcano's straits
Local port authorities issued warnings for ships traversing the strait between Java and Sumatra to exercise heightened vigilance due to potential navigation disruptions caused by volcanic activity. Boats are prohibited from entering a 3-kilometer radius zone around the volcano.
Bali and Lombok airports experience flight cancellations from volcanic disruption
Airport operations in Bali and Lombok were also affected by volcanic ash dispersal. Sixteen domestic flights to and from Bali were canceled due to the ash cloud from Anak Krakatoa's eruption.
209 aircraft movements canceled or delayed at Jakarta airport; 22,000 passengers affected
The suspension of Jakarta airport operations resulted in 209 aircraft movements being affected, impacting over 22,000 passengers. Sixteen international flights were canceled, seven were delayed, and five were reprogrammed. Affected international routes included services to Singapore (most impacted), Doha, Sydney, and Kuala Lumpur.
Jakarta airport suspends operations due to volcanic ash dispersal
Jakarta's Soekarno-Hatta International Airport suspended all flight operations on Sunday, September 6, 2026, from 01:30 local time (18:30 GMT) due to volcanic ash dispersal from Anak Krakatoa. The suspension was extended from an initial 09:30 cutoff to 13:30 local time (06:30 GMT) due to intensification of the volcano's activity. Tests confirmed ash dispersion in the airport's airspace, forcing the closure.
